Hello, I have a moderately used voice sense with the Sendero's sense nav. Software for sale. The package comes with the voice sense, sense nav, s d card with u s maps, carring case, and a Ethernet card for those who's do not have wireless in their place of business or home. I am asking $1900 for the entire package which new would be $3800. If you are interested or know someone who would be interested please contact me. thanks "God grant me the serenity to accept the things I cannot change, The courage to change the things that I can, and the wisdom to know the difference.
